Two skaters, each with a mass of 80 kg, are skating on opposite sides around a circle of radius 11 m, connected by a massless string. If each skater has an angular speed of 1.4 rad/s, what is the total angular momentum of the skaters about a vertical axis that goes through the center of the circle? This axis is perpendicular to the plane of the page. (in kg m/s) 13552 2464 4928 0 27104 If the skaters pull on the string to bring each other closer and the circle now has a radius of 8.2 m, what is their new angular speed?
